samba - May 2022 - Unable to mount with cifs.mount, but file browser mount...

I'm a but puzzled.

File server: debian stretch, louis packages 4.10.18+dfsg-0.1stretch1, AD domain,
same samba revision.

Client: mint ulyssa, aka ubuntu focal, samba 4.13.17~dfsg-0ubuntu0.21.04.2 .


Client configured with Kerberos, winbind, nss/pam; i can login into client
with domain credential, flawlessy.
After login, i can run 'caja' (Mate file manager) and mount shares from
the
server.


But i need als to automount some dirs (also homes), so i've setup pam_mount;
that does not work. But seems that cifs.mount does not work at all:

	root at archimede:~# mount.cifs //VDMSV1.AD.FVG.LNF.IT/Users/gaio /mnt
--verbose -o username=gaio
	Password for gaio@//VDMSV1.AD.FVG.LNF.IT/Users/gaio:  **********              
	mount.cifs kernel mount options:
ip=10.5.1.3,unc=\\VDMSV1.AD.FVG.LNF.IT\Users,user=gaio,prefixpath=gaio,pass=********
	mount error(13): Permission denied
	Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log
messages (dmesg)

and in log:

	[ 3285.806313] CIFS: Attempting to mount //VDMSV1.AD.FVG.LNF.IT/Users/gaio
	[ 3285.806358] No dialect specified on mount. Default has changed to a more
secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less
secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1)
specify vers=1.0 on mount.
	[ 3285.822830] CIFS VFS: cifs_mount failed w/return code = -13

I've tried every combination of 'vers=' and 'sec=' but no
one works...


What i'm missing? Thanks.

Maybe your server doesn't support SMB1? Also, SMB1 support can be compiled
out of the kernel now. Maybe you have an SMB1 server and an SMB2+ kernel?
